Interesting, things have been quiet on the Joe front, as far as non-Kreo stuff goes.

Mindbender vs. Budo was a cancelled item from waaay back during Rise of Cobra, IIRC. As was Zap vs BAT.

They'd shown off the zombie stuff at conventions and would be fools not to make them given the zombie craze and the fact Zombie-viper was a hot seller. I suspect even non-hardcore JOE fans would get some sets.
